If it weren*t a bit too long the title of this article would have been How Christians Make Themselves Miserable.
The first answer is that they do not seek the Lord*s will first. They do not put Him first. They depend upon their own strength and wisdom. They sin. They do not forsake their sin. They do not confess their sin. They do not pray. They do not study the Bible. They do not permit the Lord to correct them. They do not regularly attend a Biblical church. They reject Godly counsel. They ignore and dull their conscience. They walk in the flesh. They do not think about the Lord. And then they wonder why they are miserable. I have been there.
